The Flaming Lips and Miley Cyrus have been working together on-and-off for a few years now but, outside of a handful of songs and one crazy video, they haven’t put out much to show for it. In a new interview with Billboard, Wayne Coyne hints that may change:

At the moment we just sort of work on things as they come up, so part of this seems like something we’re working on with Miley, but we’re also working on it as a production. We make it as a song and then she gets added to it, we add more to it, and then she gets added to it again. I almost think it might be the series of songs that are Miley Cyrus songs, Flaming Lips songs on her record, then there’s the series of the same songs on our record. Ours sound like the Flaming Lips and hers sound like Miley Cyrus, but they’re the same songs.

Coyne sounds like he’s entertaining a lot of possible ways that the two of them could work together on a more public scale. For one thing, they are both working on each other’s music “a bunch” and making progress on both the next Flaming Lips album and Cyrus’ next solo album. “I think she’s probably influencing us more than we’ll be able to influence her. But that’s for the better,” Wayne adds. Some ideas floated around were the release of a release where they both put their own spin on each other’s new songs. Another possibility is a joint world tour, which Coyne has apparently been thinking about a lot:

I think we would probably do something where it’s like, “This is a Miley night and the Flaming Lips are there with her. And this is a Miley/Flaming Lips night and it would be in a different sort of setting.” It sounds insane, but I’d rather do something that sounds insane and try to make it work.

And when asked about the hypothetical concert:

(Laughs) I don’t know if it’s so hypothetical. We talk about it a lot, we just keep moving in this direction. So we’ve talked about that there’d be these giant 20-foot tall heads that we would be inside of. I’d be inside of her head with a thing over it singing from inside her brain and she would be inside of my giant head singing from inside our brains. At some point we would come down and shoot out of each other’s mouths and be there on stage.

When you start getting into production aspects, it has to happen.

Exactly, if you have ideas and you don’t pursue them then you’re not doing the thing. To me, that’s why we have people landing on the moon, that’s why we have these great computers, because someone said, “I want to do this.” And when we talk about these ideas it’s like, “Well, we’d have to do something.”
